Procedure

(4-Chloro-6-methoxy-quinolin-7-yl)-(2-morpholin-4-yl-ethyl)-amine (53 mg), 3-hydroxy-2-methyl-quinolin-4-carboxylic acid (126 mg), and 4-dimethylaminopyridine (200 mg) were suspended in o-dichlorobenzene (8 ml). The suspension was stirred at 140° C. overnight. The reaction solution was cooled to room temperature, and the solvent was removed by distillation under the reduced pressure. Water was then added to the residue, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with water and was dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by column chromatography using methanol-chloroform to give the title compound (12 mg, yield 16%).
